or closed position, the main-.burner va ves 11'0' The operating lever K of the pilot-light is arranged to move in the same direction as the lever H. The lever H is provided with a projecting pin h adapted to engage the lever K 5 when the lever H has partially completed its stroke, to open the pilot-valve, the valvelevers being shown at the end of their stroke by dotted lines in Fig. 2.

The delivery of gas to the pilot L from the passage' L is controlled by the valve O. This valve is threaded into a cuplike casing P, which is in turn threaded into the main valve casing C. The casing P is provided with the passage p through its inn-erend, and a passage p through one sid@ *fe-reif., This passage opens into an annular passage p about the valve casing, which registers with the pilot-light tube.

The valve O is provided with a Vport o which is always open to supply the pilot. The

delivery of gas through this ort is controlled.

by the adjusting screw q w ich is threaded into the valve O from its outer end. This enables the accurate adjustment of the port to1 regulate the normal flow of gas to the i ot.

p When the lever K is operated, the valve O is drawn from its seat on the inner end of the casing P, allowing a supply of gas to pass to the pilot for flashing the saine. As soon as the lever H is released, it is returned to its initial position, as stated, 'by the spring H.

A spring K is provided for returning the pilot valve to its initial position, so that the ilot valve is automatically closed when the ever H is released. The levers H and K are so arranged that the main valve is opened before the pilot is flashed, allowing the gas to drive the air from the burners and pipes 40 beyond the valve. When it is desired to cut off the gas or turn out the lights, it is only necessary to again pull on the operating chain.

The burner tubes are arranged through the outwardly projecting flange A of t-he chimj ney, so that their tips s are below the same.

" The burner tubes S are threaded upon the nipples d carried by the gas delivery ring D.

The burner tubes S are provided with air insolets s at their upper end, of sufficient size to allow the nozzles T to be inserted and manipulated therethrough. The nozzles T are threaded upon the nipples ci independently ofthe burner tubes,vv so that they may be i 5.5 placed in position or removed without in any- `wise disturbingthe tubesffthearrangement cle-arly appearing in' Figsfl and?, the same being-slipwnin detail. inthe latter figure. The .air openings 's' are lprovided with .shutter-valves S which are threaded thereon andiadapted -to be adjusted to' regulate the size of the opening' and to render the nozzles T accessible. i Needle valvest are provided for adjusting the opening of the nozzle. By

v thus forming and @arrangingy the parts, the

nozzles may be readily removed When it is desired to change or replace the same or clean them, without disturbing the other parts of the burner. This is of very great advantage, particularly with the inverted burner construction.

The outer casing G is made vertically adjustable to afford access to these parts, the casing being indicated by dotted lines in its l elevated position. The top G of the casing 7 is slidably mounted upon the pipe B. In the construction illustrated, it is not connected to the casing Gr, but it is evident that this plight be done if desired. When the4 casing :n its lower position, it rests on the S0 outwardly rejecting flange G of the band G, which orms the base of the casing.

The casing is slotted at one side to receive `the valve C, so that the valve projects outside thereof. An adjustable rest b is pro- 5 vided for the casing when in its elevated osition, as is indicated by dotted lines in ig.

1. This rest is mounted upon the collar b arrangedon the gas delivery pipe B, so that it may be swung out to the position indicated by dotted lines in Fig. 1, or swung inwardly -within the casing to allow the same to drop down onto the band G.

The globe F is carried by the globe ring F, which is hinged to an ear f on the valve so that it may be swung down as indicated by dotted lines in Fig. 1'. The globe is held in its closed position by the thumb-nut g', which engages a suitable slot in the arm g. (See Figs. 1 and 5.)

.By arranging the valve C in the position illustrated, the same is conveniently operated, and is so arranged as not to be materially heated by the lamp. r This arrangement has the further advantage of serving as a trap for any solids or condensation that might otherwise passto the burners and clog the gas delivery nozzles or otherwise inter fere with the proper operation of the burners. It is evident that with the burners arranged in the inverted position, the tendency is for the heat to be delivered to the arts above. By arranging the chimney as have illustrated and described, theheat is largely car ried away thereby, and the parts of the lamp are quite fully protected.

I have illustrated and described my imroved lamp in detail in the fornr referred by me on account. of structural simp icity and economy, and convenience in adjusting and care in use; I am, however, aware that it is capable of' considerable variation in structural details without departing from my invention.

Having thus described my invention, wh`at\ I claim as new and desire to secure by Letters Patent is: l
